Patented May 27, 1930 UNITED,A STATES FREDERICK M. vnNzrE, or*PHILADELPHIA, PENNSYLVANIA BUILDING STRUCTURE Application filed Marchy12, 11926. Serial No.v 94,291.

This invention, generally statedrelates 'to a building structure and hasmore especial relation to a fioor or like construction of conV crete.` a

According to accepted methods 'of building concrete ioor and likestructure it is quite difhcult and expensive to attach metal lath inplace to receive ceiling plaster, usually requiring the servicesof'skilled mechanics.

It is conceded by architects generally that the present methods ofapplying plaster to concrete surfaces are unsatisfactory and give nopermanent assurance ythat the work will remain in place. Work whichcarries with it a guarantee `is entirely at the risk of the contractorplacing it and case after case may be cited where the most approvedmethods are carried out with the greatest care and skill, using only thehighest grade of materials and have failed, causing great inconvenienceto the owners and expense to the contractors.

After years of study and experiment and the expenditure of large sums ofmoney, it has been positively ydemonstrated that nothing but amechanical means of fastening the plaster in place will give the resultsdesired and eliminate the possibility of any part of the plasterfalling.

The leading object of the present invention is to overcome the abovedescribed disadvantageous features and provide a structure of thecharacter stated in which a floor or the like is provided combiningeiiiciency, simplicity, and cheapness, and in whichunskilled labor maybe successfully employed in the erection of metal lath to receive theceiling plaster.

Other and further objects not at this time appearing will be hereinafterreferred to.

The invention consists of the novel construction hereinafter describedand finally lustrating a vfloor structure in` accordancey with theinvention in which the concrete is poured upon the forms.

Fig. 2, is a similar view with the forms p yremoved and the metal lathsecured in posiof a piece of lform having nailed thereupon y a metallath attachment device, prior to pouring of concrete. l Y f Fig. 4, is asimilar view illustrating the concrete poured, the form removed and themetal lath in place. n

Fig. 5, is a view' in plan of one of the' metal lath attachment devicesdetached.

Fig. 6, is a view in cross section of Fig. 5.

Fig. 7, is a view in section taken upon the line 7 7 of Fig. 4.

Fig. 8, is a fragmentary view in sectional plan taken upon the line 8-8of Fig. 6; and

Fig. 9, is a view incross section of a slightly varied form of metallatch attachment.Y

For the purpose of illustrating my invention l have shown in theaccompanying drawings two forms thereof which are at present preferredby me, lsince the same have been found in practice to give satisfactoryand` reliable results, although it is to be understood that the variousinstrumentalities of which my invention consists can be variouslyarranged and organized and that my invention is not limited to theprecise arrangement and organization of the instrumentalities as hereinshown and described.

ln the practice of the present invention the usual forms l are erectedand supported ory shoredup by beams 2, as seen in Fig. l. yfhe nextstep, as best seen at the right hand side of Fig. l, is to secure luponthe upper faces of the forms `1, a plurality of spaced, metal lath,

attachment devices, best seen in Figs. 3 .to 6. Each attachment, whichis designated 3, is composed of thin metal stamped from a single pieceof material to a shape which may be likened to thatV of a boat, see Fig.5, and each is secured in inverted position as by a nail t, to the upperface of a form l, best seen in Fig. 3.- The opposed ends of eachattachment 3 are tapered as at 5 and the opposite sides of theattachment are bent upwardly in opposed fashion 'to provide verticalside walls 6 each lterminating at its top in a laterally disposed dan e7. The outer edge of each lange7 is notc ed at 8, see Fig. 6. The sidewalls 6 of each attachment are each vgroovedvertically as at9, see Fig.6. The extreme lower and opposed parts, .as designated fat 10, arenotched, see F ig. v6. Extendedlaterally across each attachment andengaging the lower notches 10, the vertical grooves 9 and notches 8 area pair of members 11 of Wire. engage beneath an attachment and innotches 10; the ends of the Wire then extended upvwardly Within grooves9; then aroundthe flanges 7, including notches` 8,'the free ends ofl avwirebeing extended laterally in oppo.

site directions, see Fig. 7 The concrete12 having been poured to formthe door, obvi- Fig. 4. lVhile the abovedescribed struct-ure l isadapted for any desired-form of floor, ceil-l ously the metal lathattachments 3 are iirmly embedded therein. This position of parts isseen in Fig. 1. Vlith set of concrete 12 obtained, the forms 1 areremoved thusexposupon the underside of the floor a plura ity of spacedattachments 3 with the Wire parts 11 extending across each attachment.

It-is to be understood that with'tlie removalv of forms 1 the nails 4are left hangingvwithin the cavities of ther attachments v3. Metal lathof any desired type, as for example wire mesh l13, is now positioned toaccept-ceiling plaster 14, see Fig. 2. In securing the wire mesh 13 toplace the sameis lwiredasl atflto the exposed wire members 11 as bestseen in ing orlike structure it is especially eficient where ceilingbeams are formed,`as shown in the drawings, because the metal lath canbev stretched taut and very easily wired to the attachments which lattermay be positioned upon both side and vbottom Walls of a beam.

Referring now to Fig. 9, the construction is the same as that `showninthe foregoing described Vfigures except that the cross section` of theattachment is substantially Wsha'ped. Such cross sectional area admitsof the pouring of additional concrete the advantage of which is readilyapparent. By-W-shaped I mean that the central walls 3 and outer walls 6of an attachment are all inclined with respect to vone another.

Among the advantages to be claimed, meni tion may be made of thefollowing:

1. Absolutely permanent-no possibility of falling plaster. -V A 2.Unlimited guarantee-plaster willV re-v main while concrete lasts.

3; Can be lasteredover immediately--no'A waiting for c rying.

4. Easily installed. 5. Moderate in cost. r It willnow be apparent thatI have devise a novel and usefulconstruction which embodies thefeaturesof advantage enumerated as desirable in the `statement ofthe inventionThese wires are first caused to.

land the above description andrwhile I have An anchorage forlathingsheathing adapted to be embedded in concrete`con'struc tionduring the molding thereof, which comprises a generally concavedVelongated inverted shieldV which is substantiallyrboatshaped consideredlongitudinally and is of Vsubstantially W-shaped cross-section, saidshield being 'of seamless metal and adapted i kto be embedded in theconcrete with the edges` thereof flush with the outer-surface, an an-'chor wire extending across the edges of said shield and around saidshield and having transversely extending terminal anchor mem-y bers saidshield having an aperture extending through vthe top thereof for thereception of fastening means including a nail passing i through saidaperture andattached to said Vlatliing sheathing, whereby said shieldand transverse anchor member may be secured to the inner surface ofconcrete molding forms.'`

In testimony whereof, I have hereunto signed my name.
